<h3>Import Landsat</h3>

<p>The Landsat reader enables the Sentinel Toolbox to import Landsat TM data products in either the Fast format
    (Landsat5) or in GeoTIFF (Landsat4,5) format.
    The instruments ETM+ (Landsat7), OLI, TIRS (Landsat8) are only supported in GeoTIFF format. GeotTIFF format of Landsat8 processed by ESA is also supported.
    MSS data from Landsat 1 to 5 is also only supported in GeoTIFF format.
</p>

<p>In 2016, the USGS started reorganizing the Landsat archive into a formal tiered data Collection structure.
    This data collection structure ensures that Landsat Level-1 products provide a consistent archive of known
    data quality to support time series analyses and data "stacking", while controlling continuous improvement
    of the archive and access to all data as they are acquired.
    See <object classid="java:org.netbeans.modules.javahelp.BrowserDisplayer">
        <param name="content" value="https://www.usgs.gov/land-resources/nli/landsat">
        <param name="text" value="<html><u>Landsat mission</u></html>">
    </object>.
</p>

<p>Collection 1 products are supported by SNAP.
    The interpretation of quality bands are different for both
    (please, note also that the quality interpretation has been corrected from previous versions of SNAP).
